ObjectiveTo summarize the surgical treatment and explore factors which influencing prognosis of hilar cholangiocarcinoma. MethodsClinical data of 189 cases of hilar cholangiocarcinoma who treated in our hospital from Jan. 2000 to Dec. 2010 and clinicopathological factors that might influence survival were analyzed retrospectively. A multivariate factor analysis was performed through Cox proportional hazard model. ResultsOf 189 cases, 62 cases received radical resection, 54 cases received palliative surgery, and 73 cases received non-resection surgery. Operative procedure (RR=0.165), differentiated degree (RR=2.692), lymph node metastasis (RR=3.014), neural infiltration (RR=2.857), and vascular infiltration (RR=2.365) were found to be the statistically significant factors that influenced survival by multivariate factor analysis through the Cox proportional hazard model. ConclusionsRadical resection is the best treatment for hilar cholangiocarcinoma. Skeletonized hepatoduodenal ligament, complete excision of infiltrated nerve and blood vessel are important influence factors to improve the prognosis of hilar cholangiocarcinoma.
